OPERATING INSTRUCTION FOR THE GAS LIFT, TILT & TENTION CONTROL

Please note the following: 

• The chair will need to be fully assembled before the following actions can be carried out. 
• In order for the gas lift and mechanism to engage, it is advisable to sit fairly heavily on the chair prior to initial use. 
• In order for the gas lift to function properly, the user should sit as centrally on the chair as possible. DO NOT lean heavily to one side as this will damage the mechanism.  

FUNCTIONS ON THE MECHANISM

1.      GAS LIFT / SEAT HEIGHT ADJUSTMENT

• This is controlled by the lever on the front right hand side of the chair. A‘twisting’ action should be applied to the plastic paddle at the end of the lever. N.B There is ‘loose travel’ on the paddle before it fully engages, so it is necessary to push very firmly past this point – it is a common belief that the lever is not functioning properly because caution prevents the user from applying sufficient pressure. The gas lift will not raise the chair if the users weight is on the seat – in order for the seat to raise, the user would need to take their weight off the chair. Conversely, in order to lower the seat, the weight of the user is needed to force the chair down.

2. TILT FUNCTION / Locking the backrest in the upright seated position
3. TENSION CONTROL

• The same lever that is used for the height adjustment is the control of the tilt movement on the chair. If the lever is pulled out, it will release the tilt mechanism and it will set the backrest in free float mode. If the lever is pushed back in (with the seat in an upright position only) it will lock the chair in place.

• When the chair is in tilt mode, the tension can be adjusted to suit the weight preference of the user. Turn the handwheel clockwise to increase the tension and anticlockwise to decrease the tension.
